HAY AND STRAW BURNER.

SPECIFICATION forming part of Letters Patent No. 250,961, dated December13, 1881.

Application tiled October 5, 1881.

To all whom it may concern:

Be it known that we, MARTIN B. PARKER and RICHARD W. RICHARDS, of BlueEarth City, in the county of Faribault and State of Minnesota, haveinvented certain new and useful Improvements in Hay and Straw Burners,of which the following is a specification.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the iigures.

Figure 1 is a sectional side elevation of our improvement. Fig. 2 is asectional plan View of the same, taken through the line x x, Fig. 1.

The object of this invention is to provide suitable means for burninghay, straw, and other light fuel for cooking and heating purposes.

A represents the body of the burner, which may be made of cast, boiler,or sheet iron, or partlyof cast-iron and partly of boiler or sheet Iron.

B is a funnel or spout connected with the opening C in the burner forconvenience in introducin g lthe fuel. The funnel B may extend through apartition into a fuel-room, and is provided with a door, D, at its outerend. The funnel B is provided with a sliding door, D', inserted throughthe outer end of the said funnel, and which serves the double purpose ofpushing the fuel through the said funnel into thel rechamber, and ofpreventing the funnel from becoming unduly heated; or the funnel B maybe omitted and the fuel introduced through the opening C, in which casethe said opening is provided with a door. The fuel,whi1e being burned,is compressed between two grates, E F. The upper grate, E, isstationary, is placed a little distance below the top of the burner, andis attached to the upper ends of rods G, the lower ends of which areattached to the bottom of the burner A. The rods G serve as guides tothe grate F when moving up and down, and also keep the fuel away fromthe sides and ends of the burner, to form open spaces for the freeescape of the smoke and gaseous products of combustion.

To the corners of the grate F are attached the ends of chains H. Theforward chains H (No model.)

passlover guide-pulleys I, and pass back be- 5o raised and lowered byturning the shaft J.

The shaft'J is turned by means of a crank, K, attached to its projectingend, and is held from being turned by the weight of the grate F by apawl, L, which engages with a ratchet-wheel,

M, attached to the said shaft. Air to support 6o combustion entersthrough openings N in the rear wall of the burner, and in the frontdoor, O, of the said burner, which openin gs are regulated by slides Pin the ordinary manner.

Enough space can be left beneath the grate F to receive the ashes from adays burning 5 or the ashes may be received in a pan, Q, slid into thelower part ofthe burner; or the bottom of the burner can have an openingformed in it, closed by a slide and connected with a pipe 7o or spout'leading into an ash-receiver in the cellar, and through which the ashescan be discharged when desired.

In the upper rear part of the burner, between the upper grate, E, andthe top of the said burner, is secured a partition, R, to direct theproducts of combustion beneath the boilerholes S. The partition R ismade in two parts or sections, the forward part or section sliding uponthe rear part, so that the main volume 8o of heat can be directedagainst any desired part of the top of the burner.

To the rear part of the top of the burner A is secured an oven, T, thewalls of which are made double, so that the space U between the saidwalls will serve as a iiue to conduct the products of combustion to thesmoke-pipe V. The space or lue U is connected with the interior of theburner A by an opening, W, within which is placed a guide-plate, X, todivide 9o the products of combustion and cause them to pass up upon bothsides of the oven T. When the oven is in use a part of the products ofcombustion can be allowed to pass through an opening, Y, in thepartition R, and

be guided to the opening W by a plate, Z. The plate Z, or both theplates Z X, can be movable, to adapt them to serve as dampers toregulate the draft. The ashes are prevented from passing through theopening W Y by wiregauze screens a.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a hay and straw burner, the combination,with the body A, ofthe stationary grate E, the supporting-rods G, themovable grate F, the chains H, and the crank-shaft J, substantially asherein shown and described,where by the fuel can he compressed whilebeing burned, and a draft-space kept open all around the said fuel, asset forth.

2. In a hay and straw burner, the combination, with the body A, havingopening` YV, the

lpartition R, having opening Y, and the doublewalled oven T, of theplates X Z, substantially as herein shown and described, whereby theproducts of combustion are directed into and zo distributed through theoven-flue, as set forth.

3. In a hay and straw burner, the combination, with the body A and thepartition R, of the wire screens a, substantially as herein shown anddescribed, whereby the ashes are 2 5 prevented from entering` the Hue ofthe doublewalled oven, as set forth.
